Oracle's "Unbreakable Enterprise Kernel"

Strictly speaking that is not true. No one "accepts" an ordinary license. The liability is entirely in terms of getting sued if you go beyond the rights granted to you by the license itself (or the other rights you have license or no license).

Of course this wanders into the bizarre world of shrinkwrap and other post-sale/post-delivery "licenses", and how and why they actually do what they claim to. At least there is substantial and identifiable consideration in most cases there though, making the arrangement look much more like a contract than a blanket grant to whoever and whomever.
